Abstract
The utility model belongs to petroleum downhole operation tools and particularly relates to a switching type sliding sleeve fracturing valve. The switching type sliding sleeve fracturing valve comprises an outer sleeve (1), a sealing part (6), a pin (3) and a lower joint (5), wherein the lower end of the outer sleeve (1) is in threaded connection with the lower joint (5), a sliding sleeve (2) which is positioned and connected by the pin (3) is installed inside the outer sleeve (1), a C-shaped ring (4) is installed inside an outer ring groove of the sliding sleeve (2), the outer portion of the C-shaped ring (4) is connected with an inner ring groove of the lower joint (5) in an elastic mode, and the sealing part (6) is located between the outer sleeve (1) and the sliding sleeve (2). According to the switching type sliding sleeve fracturing valve, the C-shaped ring is used for elastic connection, the switching of the sliding sleeve and the load required by conversion of switching states are achieved through the elasticity of the C-shaped ring, and accurate switching states of the sliding sleeve are guaranteed during exploitation.
Description
Technical field
The utility model belongs to the oil underground operation tool, but particularly a kind of switching regulator sliding sleeve fracturing valve.
Background technology
At present, but switching regulator sliding sleeve fracturing valve not locking after sliding sleeve is opened and closed both at home and abroad, and the easy sliding sleeve play phenomenon that produces, cause on off state chaotic in recovery process, affects recovery ratio.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned technical deficiency, provide a kind of can the elastic locking structure, prevent sliding sleeve play in recovery process, but guarantee on off state switching regulator sliding sleeve fracturing valve accurately.
The technical scheme that the utility model technical solution problem adopts is: but the switching regulator sliding sleeve fracturing valve comprises overcoat, seal, pin, lower contact, be characterized in the lower contact that is threaded of overcoat lower end, the sliding sleeve that is located by connecting by pin is equipped with in overcoat inside, C type ring is housed in the sliding sleeve outer groove, C type ring is outside to be connected with lower contact inner groove elasticity, and seal is placed in respectively between overcoat and sliding sleeve.
The beneficial effects of the utility model are: but the switching regulator sliding sleeve fracturing valve adopts C type ring resilience to connect, and realizes the sliding sleeve switch with the elasticity of C type ring, and the required load of switch state, in the assurance recovery process, the sliding sleeve switch state is accurate.
Description of drawings
Illustrate with embodiment below in conjunction with accompanying drawing.
But Fig. 1 is switching regulator sliding sleeve fracturing valve structure chart.
Fig. 2 is C type loops composition in Fig. 1.
In figure, the 1-overcoat; The 2-sliding sleeve; The 3-pin; 4-C type ring; The 5-lower contact; The 6-seal.
The specific embodiment
Embodiment, with reference to accompanying drawing 1,2, the lower contact 5 but overcoat 1 lower end of switching regulator sliding sleeve fracturing valve is threaded, the sliding sleeve 2 that is located by connecting by pin 3 is equipped with in overcoat 1 inside.Be equipped with in sliding sleeve 2 outer grooves and be with flexible C type ring 4, C type ring 4 is outside to be connected with the inner groove elasticity of lower contact 5, and seal 6 is placed in respectively between overcoat 1 and sliding sleeve 2.
But the course of work of switching regulator sliding sleeve fracturing valve is: going into the well with the pressure break completion tubular column puts in place, replace base sealed packer, but pitching drops down onto in the sliding sleeve 2 of switching regulator sliding sleeve fracturing valve, suppress and cut off the rear sliding sleeve 2 of pin 3 and open, by C type ring 4 elastic lockings, the pressure break passage is opened, and following passage is stopped up, and carries out pressing crack construction.Open flow after pressure break can be exploited simultaneously, but also can the switching regulator sliding sleeve fracturing valve be closed by switching tools, by C type ring 4 elastic lockings, realizes the exploitation of layering choosing layer.
Claims (1)
1. but switching regulator sliding sleeve fracturing valve, comprise overcoat (1), seal (6), pin (3), lower contact (5), it is characterized in that the lower contact (5) that is threaded of overcoat (1) lower end, the sliding sleeve (2) that is located by connecting by pin (3) is equipped with in overcoat (1) inside, in sliding sleeve (2) outer groove, C type ring (4) is housed, C type ring (4) is outside to be connected with lower contact (5) inner groove elasticity, and seal (6) is placed in respectively between overcoat (1) and sliding sleeve (2).
